MILK-BOTTLE STOPPER.

Specification of Letters Patent.

Patented Feb. 4, 1913.

Application filed September :19, 1911. Serial No. 650,084.

To all whom it may concern:

Be it known that I, THOMAS B. SLUBY, a citizen of the United States, residing at Canonsburg, in the county of Washington and State of Pennsylvania, have invented new and useful Improvements in Milk-Bottle Stoppers, of which the following is a specitication. v

This invention relates to improvements in stoppers for bottles, jars and the. like! In carrying out my invention it is my purpose to provide an extremely simple and thoroughly effective closure which may be readily applied to the neck ofa bottle or the like and which may be readily removed therefrom when desired.

It is one of the primary objects of my invention to provide a stopper of this character which embodies few parts, which is cheap to manufacture, and which will hermeticallv seal the neck of a bottle or the like.

With the above recited objects in view, the invention resides in the construction, combination and arrangement of parts set forth in and falling within the scope of the appended claim.

In the accompanying drawings Figur e 1 'is a sectional view through a bottle or jar neck and showing my improved stopper in applied position thereon. Fig. Qis a similar-view illustrating the stopper when in a position to be removedfrom the neck of a bottle or jar. Fig. 3 is a central longitudinal sectional view taken through the stopper. Fig. 4 is a similar view of a modified form of the stopper.

Referringmow to the drawings in detail, the numeral 1 designates the mouth of a bottle or jar and 2 the, stopper therefor.

--The said bottle or jar as illustrated in the accompanying drawing, is provided Within the neck portion thereof with an inwardly extending annular enlargement 3' located at a point below the upper edge of the neck and inclines downwardly and inwardly as has been shown. The stopper 2 comprises essentially a head 3 the area of which being greater than the c'ircumference'of the bottle neck. The head 3 is constructed from some suitable hardened material and is of a size sutlicient'to overlie and close the mouth ot the jar or bottle The numeral 4 designates an eye which is secured to the head, the said eye being adapted for the reception of one of the end links of a chain 5, the opposite end link being secured to the bottle neck as at 6. The head 3 is centrally provided with a suitable opening through which extends a stem 6, said stem being also connected with a disk 7 which is arranged below the under face of the head 3. The stem is also adapted to pass through an opening provided in the under face of a compressible cup-shaped member 7, preferably formed of rubber, and to sustain the said cupshaped member upon the disk 7, and the portion of the stem projecting within the head 3 is eccentrically pivoted with a lever 8. 4

As illustrated in Figs. 2 and 3 the sides of the compressible cup-shaped member 3 are curved or bulged outwardl from their bottom face toward its open ace, or that portion which contacts with the under face of the head 3, and upon throwing the lever 8 in one direction its cam face engaging with the outer face of the head 3 will more tightly force the botto of the said c0m'-, pressible member toward the head 3, thus expanding the sidespf the'said member to force the same tightly into engagement'with the inner face of the bottle-neck. It may be here stated that the compressible member is normally of a size to be snugly received within the neck of the bottleor jar, and that the same may be employed asan ordinary stopper when it is not desired to hermetic-ally seal the bottle or jar.

In Fig. 4 I have illustrated a slightly modified form of the device. In this figure a cup-shaped and expansible element is employed in connection with the head 3. In this Fig. 4 I have illustrated a flanged mem her which is arranged in an inverted position with relation to that shown in the re maining figures of the drawing. The flanged member is, of course, compressible and arranged within the said flanged mem her is a disk which is attached to a headed member 10, the same passing through suit-. able openings in the compressib e flanged member and in the head 3, the upper ex tremity of this headed member 10 is pivotally connected with a camlever 12. The

inner wall provided by the flange of. the compressible member is beveled or inclined from its outer edge toward its under face and it will be noted-that by operating the hand lever the disk or member connected with the headed element 10 will be forced to ride upon the said inclined wall to exert In combination a bottle provided within the neck thereof with an inwardly extending annular enlargement, said enlargement being located at a point below the upper edge of the neck and having its inner face inclined downwardly and inwardly, a plate resting upon the upper edge of the neck, a compressible member located within the neck and extending from the plate to 21 point below the under side of said enlargement, and means by which said member may be compressed so as to force the central portion thereof into effective engagement with said inclined face and a portion thereof inwardly beyond the upper side of 20 said enlargement.

In testimonfy whereof I aflix my signature in presence 0 two witnesses.
